Milwaukee Brewers C Mike Rivera lost 25 pounds this offseason as he prepares to battle for the backup catching duties with Cs George Kottaras and Wil Nieves, according to MLB.com's Adam McCalvy. "I feel like they took it away from me after three years here of doing a pretty decent job," Rivera said. "I lost 25 pounds and I'm in the best shape I've ever been in baseball. I feel comfortable that I know everybody. Hopefully, I get the chance to make it hard for them to make a decision."
